Correlation between Left Ventricular Mass and Cardiac Troponin T in Cardiac Surgery.

Abstract

Cardiac troponin levels might rise significantly after cardiac surgeries as a surgical outcome rather than ischemic myocardial damage alone, making the diagnosis of postoperative (type 5) myocardial infarction challenging. Previous studies have demonstrated that cardiac troponin is related to left ventricular mass, but this correlation was not investigated after cardiac surgery. We aimed to study a possible correlation between postoperative cardiac troponin levels and left ventricular mass index in patients who underwent cardiac surgery to refine the diagnosis of type 5 myocardial infarction, but observed no such correlation regardless of preoperative troponin levels or surgery type.
